" 'Y My inventionrelates to Wall-board whichis usedinbuildings'. TheWall-board is-secured Awhen the plasteris applied'thereto therefore, f the Wall-boardwrnust not expand when the vplasteris .applied toit, orif itdoes'expand fit must'be made 'so that this expansion will not Ycause buckling; A

' It is 'an `object of inyinvention to provide .afwall-board Which will not buck'levvhen the plaster is appliedto it. I' Another requirement of a good Wall-board is that it be designed so 'that the plaster may be securely keyed to it;I otherwise there is a liability ofthe plasterfalling from place or creeping, due to its r'ovvn Weight or from vibration.` f It :is-:accordingly another of the objects of thisY .invention to provide a Wall-board to which the plaster will securely key itself.

llt is important that 4the Wall-board be rigid y and strong iso that it will form a good base for the plaster; and it isone of the objects of my invention yto provideia Wall-board which has rigidness` and Astrength when "attache-d to the supporting meinbers of the Wall or ceiling. f 1 f f 'th'e'r objects and advantages' of the/invention Will be `I'n'ade :evident in the following `de- .,scrip'tionwhic'h is taken in*` connection With the drawing?.

Then rows :of slots divide the 'sheet 1l tending 14. The ends off the slots 'l2 of l'alternaterows terminate in .horizontal "unsern-.er1 best-in nig. rwhichf shows an Y planes 'A- so 'that the bridges .formed loetween :ends ofthese Lslots rest the same horizontal plane. Theends rofthe slotsot the Iother rows ot'zslots terminate in horizontal planes 'BeB 'which extend parallel to the horizontal planes .A--sA-i bint-are fin staggered relationship. f The ends* of the .slotsy *of 4adjacent rows'ozf slots yoverlap in ahorizontal plane as illustrated;` for"example7 the yupper end o'ffone; slot overlaps with the lower end of aslot inan adjacent row. f Vkt-the central part of-eachslot 12 .is anexpansifon joint '.17 which isv .formed-by vcutting notches 18 vin adjacent strips 14. f

Thewall-board5 Y r illustrated best in Figs. `2 and :8, also includes lacings r2() Whichvmay be .made of different materials lontane pref.- `erably ormedowo'od or chemically treated cardboard These lacings 20 extend horizontal planes and through the overlapping ends :of the :slots l2. The purpose of the la`c ings 20 is to bend *adj acent portions of each strip 14:` in opposite :directions so thaty each v strip is Wave-:shapedas illstrated .in Fig. 8. The lacings 20 are entendedfover alternate strips 14 and under the other strips 14 so :that a `sort of ay wave is( provided. Each slot 12V in the preferred formof my invention Ais long enoughto have a lacing Q0 extended through each end thereof. At the 'central part of each of the slots 12 the adjacent strips 14' are extended in crossing planes. Before' the :lacy ings are placed the strips allV .rest .in a com` Y .whichiform a part voiithewall construction.

' of are in diiierent planes. Thel purpose .ofk this is to permit an expansion of the sheet 11 l without buckling,` a further Yexplanation ofl mon plane, and .the expansion notches -18 are likewise in a kcornrnon plane. When the adjacent strips are bent into'a wave shape by the lacings 20, the adj acentstrips wherethey cross` the normal plane of the sheet 11 are crossed as' previously mentioned, and the expansion notches* 18 of each` expansion joint 17 aredisalignedfso' that side walls l21"there which will be made later. 4. l Adverting particularly to Fig. 2', itdwill be seen that the lacing'sf20 extend in horizontal.

planes' at right angles to vertical studs .22

Thewall-board is. attached vto the studs 22 l "by nailsi23which are driven through the lac- .ings20 into the studs. The lacings 20. provide a .rigid supporty for thesheet 11` since they are secured tothe vertical studs 22. The

extendingof the lacings 2O Yin a horizontal iplaneis an important part of this invention ybecause of the fact that rigidityis thereby came into Contact with eachother. A'

vobtained; A further feature of theconstruction illustrated. in the figures in considera- `tionfA is that the slots 12-extend diagonally;

that is, ,neitl'l'erv horizontallynor. vertically..

The advantage resulting vfrom'this V,feature is that plasterwhen applied will securely key,

to the wall-board. The reasonis that the .slots are not vertically disposed. If the slots -Were vertically disposed, the plaster would Vtend to slide downward, since the wave-strips would oii'er no opposition; consequently' the plaster would creep and be very uneven, and in many cases would free itself from the wallboard. .In Figs. 4 and-'5 I illustrate afportion of the wall-board and yone .of the expansion joints 17 lIn Fig. 4 the plaster has notbeen applied. In Fig. 5 I show a 'coating `of plasterv 26 applied to the wall-board." If

the wall-board is made ofcardboard, the expansion thereof ywill be very small, 'and the .wall-board will have an appearance not very dissimiliar to that shown .in Fig. .4. lOnthe Aother hand, if the. wall-boardis' made of wood, the expansion will bequite material l,and the wall-board .will :have: an appearance as shown in Fig. 5. Theadjacent strip`s-14 Vexpand laterally sol'that bottoms 27 -fofthe this nature the wall-board cannot be made .of

wood because considerable buckling would result when the edges of the adjacent strips vThe forni ofthe invention, just described, i

is adapted for use on vertical walls or on ceilings or on horizontal walls. When the wall-board is used on a ceiling, the `lacings .'2'0 extend across the joists',y and are nailedV thereto substantially as shown in Fig. 2.-

When Athe wall-boardfis used in thismanner the ydirection .of extension of the?. slots and lacings l12 and strips 14 'respectively are immaterial. The direction of4 extension of these `slots', and strips, howeverare extremely im- '.portant when the wallboard is used in a vertical position as shown in Fig. 2. The

forming vof slots. and. strips diagonally with respect to the lacings is a material departure from any otherwall-board on kthe market today orl known tothe-inventori. f 'Y 'In` Fig. 6 I show a second form ofvmyinvention.. This form of the invention includes a sheet 40.which,.as in the lirst o-rmfof my;v '.invention, is Vpreferably* made. of "ai lire Vprooed cardboard. The sheet40 has slots 41 formed therein which are arranged in diagonal rows, the slots Vof each row being separated by bridges 42. Inthis form of= the invention'the slots'41 are rathershort,

and ther bridges of each of the rows'ofslots arerin aligned horizontalplanes- The slots.

of adjacent rows of slots are not overlapped as in the first form of thefinvention. 'Ex'-l tendedthrough the slots 41 are lacings 43 whichserve the purpose of bendingstrips 44 4formed between the lrows ofslots into a wave-shaped form of substantially. the same shape V,as .in the rst forinof the invention." .The important difference between'the form of the invention now being described andthe first form of the vinvention y'previously described is that the slots are quite short and only long enough to have a single lacing 43 extended therethrough, the laeings being extended through the central parts of the slots. i

Inthis form of the invention-no expansion joints are provided. This form of the invention is adapted .primarily forwall-board which is'not intendedto ybemade 'ofa mate- .rial which will expandv when plaster. is applied thereto. The slots W41. however, are open so that a slightarnount of' expansion may occur withoutany buckling.. 1

In Fig. 7 I illustrateathird form of my invention'which has a sheet 50 in which slots 51 are formed. The slots 51 are formed in rows of slots which are parallel, the slots of each row being separated'by bridges 52. In this form of the invention the lslots all extend vertically and areV separated by4 vertical strips 53. The slots are not. overlapped as in the first form of the invention, and the Vbridges between the slots of the different rows vof slots are in horizontal alignment. Lacin are extended through the slots of the'different' rows of slots, and the stripsf53 are bent into wave shape as inthe other forms of the invention. In this form of the 'invention the lacings 55..extendv horizontally, yand f there is a liability falling from'y place.

the wall-board is as'rigid as inthe other vforms ofthe invention. lustrated in Fig. l( is primarily adapted for use on ceilings and wherever the wall-board rests in a horizontal plane. VIt islnot well Y adapted, however, for vertical walls Vsince I claim as my invention:
